| 摘 要： | 针对燃用劣质煤的循环流化床（CFB）锅炉，通过锅炉本体设计的改进、烟气净化系统的优化，提出炉内清洁高效燃烧+炉内细石灰石粉脱硫+炉内SNCR脱硝+尾部烟气循环流化床半干法多污染物联合脱除的技术路线，并在2台300 MW CFB锅炉上进行验证实验。结果表明，通过燃烧调整、脱硫与脱硝的匹配，CFB锅炉可以顺利实现NOx、SO2和粉尘的超低排放，并且在经济性方面较传统工艺具有明显优势。

| Abstract: | By improving the boiler design and optimizing the flue gas cleaning system, a new technical route is proposed for CFB boilers burning low-rank coals, in which four technologies are implemented together, i.e., the ultra-clean and high-efficiency combustion in furnace, desulfurization with small limestone in furnace, SNCR denitrification system and joint removal of multi-pollutants in semidry flue gas cleaning system. The verification experiment are carried out on two 300 MW CFB boilers. From the results it is shown that ultra-low emission of NOx, SO2 and dust can be realized by way of combustion adjustment and coordination of the desulfurization and denitrification. Moreover, this technical route has obvious advantages in economy over the conventional technologies. |
